A coupling structure of a knob for a flip-up glass is provided to employ a cap rotatably coupled to an insert nut bound to a fixing bolt, thereby preventing the insert nut from being separated from the fixing bolt. A coupling structure of a knob for a flip-up glass includes a support part(20), a fixing bolt(40), an insert nut(50), and a knob(60). The insert nut(50) is coupled to the knob(60) through a cylindrical cam rotatably coupled to the insert nut(60). An outer circumferential groove is formed along an outer peripheral surface of the insert nut(60). An inner circumferential groove is formed by cutting away a portion of an inner peripheral surface of the cap corresponding to the outer circumferential groove. A plurality of outer circumferential grooves, inner circumferential grooves, and bearings are provided in the longitudinal direction of the insert nut and the cap.
